my .410 that is about 30 yrs old that I found in my grandpas closet when I was 5
it had been shot only about 50 times .its deadly accurate and is , in my opinion, better than a 12 or 20 because it gets your aiming and shooting fundamentals down, if you can hit it with a .410 you can hit it with a 12, plus less recoil and since it is single shot it also helps you get good with making that one shot count
